SOAP-DISPENSER.

Specification of Letters Patent.

Patented Nov. 20, 1917.

Application filed. December 17, 1915. Serial No. 67,309.

To all whom it may concern:

Be it known that 1, WILLIAM. F. HATCH, a citizen of the United States,and resident of lllilwaukee, in the county of Milwaukee and zit-ate ofWisconsin, have invented new and useful Improvements in Soap-Dispensers,of which the following is a description, reference being had to theaccompanying drawings, which are a part of this specification.

This invention relates to improvements in soap dispensersmoreparticularly adapted for dispensing liquid soap.

It is one of the objects of the present invention to provide a soapdispenser which will supply or measure out a limited quantity of soapfor immediate use in hotels and on trains or in public or other placeswhere it is desired to maintain the soap in a perfectly sanitarycondition, and which is also serviceable in etfecting an economical useof soap.

A further object of the invention is to provide a soap dispenser whichwill measure a predetermined quantity of soap and hold the measuredquantity of soap in an inclo sure and permit the patron to use as muchof the measured quantity as desired thus saving the unused portion.

A further object of the invention is to provide a soap receptacle havingmeans for measuring a predetermined quantity of soap in an inclosureconstructed to prevent the discharge of soap therefrom until thequantity has been measured therein and also constructed to prevent thecharging of said inclosure while soap is being discharged therefrom.

A further object of the invention is to provide a soap dispenser whichis of simple construction, is strong and durable and is well adapted forthe purpose desired.

With the above and other objects in view the invention relates to theimproved soap dispenser and its parts and combinations as set forth inthe claims, and all equivalents thereof.

In the accompanying drawings in which the same reference charactersindicate the same parts in all of the views:

Fig. 5 is a sectional detail view of the coin controlled mechanism takenon line 5'5 of Fig. 1;

Fig. 6 is a detail sectional view taken on line 6--6 of Fig. 5; and

Fig. is a front View of a plurality of soap dispensers connected to aremote source of soap supply.

Referring to the drawings the numeral 10 the casing and is provided witha downwardly extending discharge pipe 14: to feed the soap by gravity tothe measuring tube 15 connected to the lower end of the dis charge pipeand extending downwardly therefrom. A controlling valve 16 havingcomparatively a large port 17 is interposed between the discharge pipe14 and the measuring tube 15 and is provided with a cranked handle 18for opening and closing the same. The lower end of the measuring tube 15is also provided with a valve 19 having comparatively a small port 20and a controlling cranked arm 21. A discharge pipe or nozzle 22 extendsfrom the lower or discharge valve 19 to a point outside of the casing10.

Positioned adjacent to the controlling valve 16 is a reciprocal valvebar 23 which slides in transversely extending guide plates 24 which areconnected to the opposite sides of the casing 10. The valve bar isprovided on one edge with a projecting lug 25 having a horizontallyextending slot 26 through arm 26 forming part of the coin controlledmechanism 27 which is mounted on the casing and has a portion extendingthereinto. The lever arm 26 forms part of a revoluble drum :28 which isturned manually in one direction by a connected and out wardlyprojecting handle 29 and is retrieved in the opposite direction by acoiled spring 30. One end of the spring is connected to the casing 10and the opposite upper end 30 is connected to and winds around the drum28 when said drum is turned manually by the handle.

The coin controlled mechanism comprises the outer shell 31 having a coinreceiving slot 32, the back plate 33 and a revoluble coin disk 34mounted thereoetween. The coin disk is provided with a coin recess 35which is in register with the slot 32 when said disk is in normal coinreceiving position and also with peripheral locking notches 36, 37 and38 which are engaged by locking dogs and i0 yieldingly and pivotallymounted in the shell 31. Another yielding dog el is yieldingly pivotallymounted in a side recessed portion or" the shell and its shouldered endportion 41 is positioned to swing into the coin disk as and engage theedge portion 34 thereof and stop movement of said disk in the event thatthe handle is turned without inserting a coin in the coin slot. Thelower hooked end of the dog lO engages the shoulder of the notch 38 andstops further progress of said disk in case a coin or slug of lessdiameter than the proper coin is inserted in the slot.

lVhen a coin of the proper diameter is inserted in the slot the saidcoin will engage the cam edge portion of the locking dog $0 and swingthe hooked end portion 4C0 out or" the path of movement of the shoulderof the notch 38. The dog 39 is swung upwardly by its spring when inregister with the disk recess 36 and the said dog then enters thenotches 37 and prevents retrograde movement of the disk until it hascompleted its required movement. hen the disk has been turned to itsfull extent the coin will drop out of the disk recess through the shellopening 43 and into the casing 10 and the dog 39 will swing into therecess 38 and when the disk is retrieved "by its spring the said dogwill be swung 1,2ee,91e

to the position shown in Fig. 5. The disk 34: i mounted upon and turnswith the portion of the handle 29 which extends through the shell and isconnected to the drum 28 and to the lever arm 26.

From the description thus far given it will be seen that when the propercoin is deposited in the slot of the coin controlled mechanism and thehandle thereoi is turned the valve rod 23 will be pulled down and thecontrolling valve 16 opened to discharge the liquid soap from the soapreservoir into the measuring tube 15. As the port of the controllingvalve is comparatively large the said measuring tube will be quicklyfilled with the soap during the turning of coin mechanism handle.

T he discharge of the soap from the measuring tube 15 is controlled bythe discharge valve 19, before mentioned by means of a push member 1%wnich projects through the casing and at its inner end is connected tothe cranked arm 21 by a slotted connection 21. The said push member 4%ex tends into the casing horizontally and through and is guided by atransversely extending guide plate -l5 which is attached to the oppositesides ofthe casing 10. A coiled spring l6 surrounds the push member 4: 1and is interposed between the guide plate 45 and a transverse pin l?extending through the push member to normally nold the discharge valvein closed position so that as the push member is pushed inwardly thevalve will be opened to discharge the desired quantity of liquid soapthrough the discharge nozzle tube up to the extent of the measuredquantity within the measuring tube.

As the port of the discharge valve is comparatively small the soap willflow therethrough at a slower rate of speed than the other valve and theuser may hold the push member in its inner position until all of thesoap is discharged or the push member may be controlled to discharge thesoap in quantities less than the whole amount until the full amount ofthe measured quantity of soap is used, and in case the measured quantityis not used the remaining portion will he a gain for tie machine as itwill not require as much soap to fill up the measuring tube for the nextpatron.

In order to prevent the user from opening both valves at the same timeand surreptitiously drawing out a greater quantity of soap than themeasured quantity, the push member is provided with an upstanding stoplug 48 which is positioned just in front of the lower end portion d9 ofthe reciprocal member 23 so that when the reciprocal member is in itslowermost valve opening position, the lower end portion -l9 will be inthe path of movement of the lug lS of the push member, and conversely,when the push member is pushed inwardly the lug 48 Will be immediatelybeneath and in the path of movement of the reciprocal member and preventmovement of said member until the push member has been retrieved by itsspring to its outer normal position.

In the modified form shown in Fig. 7 a plurality of dispensing devicesare connected to a soap reservoir 13 by pipes 1% for use in hotels orother places requiring a number of the devices to supply all of thedevices With soap from the one tank or reservoir.

From the foregoing description it Will be seen that the soap dispenseris of simple construction and is Well adapted for the purpose described.
